MEP Engineering & Design Solutions in Oregon, United States

Architecture-Integrated MEP Design for Oregon’s Decarbonization Mandates

National MEP Engineers serves as a technical extension of your architectural team, ensuring your projects comply with the 2025 OSSC and the latest Oregon Energy Efficiency Specialty Code. As Oregon moves toward mandatory Building Performance Standards (BPS) for large commercial structures, we prioritize producing meticulous CD sets that bridge the gap between architectural intent and energy-neutral reality. Our Oregon-registered PEs oversee every trade from SD through final construction documentation, ensuring that complex mechanical and electrical systems are seamlessly integrated without disrupting your design’s aesthetic or functional goals.

Our Top MEP Engineering Services in Oregon

Mechanical Engineering Design

Oregon’s climate demands a careful balance between indoor air quality and energy conservation. We design HVAC systems in strict compliance with the 2025 Oregon Mechanical Specialty Code (OMSC), focusing on high-efficiency heat pump technology and advanced heat-recovery ventilation (HRV). Our mechanical CD sets provide the technical clarity needed for precise load calculations, ensuring your building meets the state’s aggressive decarbonization targets while maintaining superior occupant comfort.

Electrical Engineering Design

We address the rising demand for EV charging infrastructure and grid-ready systems through our electrical designs. We deliver comprehensive power distribution and lighting layouts that comply with the 2023 Oregon Electrical Specialty Code (OESC) and the latest NEC amendments. We ensure your electrical CD sets support both modern architectural lighting and the heavy power requirements of Oregon’s growing tech and residential sectors by producing detailed circuitry and riser diagrams early.

Plumbing Engineering Design

The plumbing systems in Oregon not only need to comply with the 2023 Oregon Plumbing Specialty Code (OPSC) but must also be high-performance. Our focus includes high-efficiency water delivery, sustainable waste management, and advanced stormwater solutions tailored to the Willamette Valley’s rainfall patterns. We optimize every plumbing design for material efficiency and trade coordination, ensuring the infrastructure fits perfectly within your architectural envelope.

Fire Protection Engineering Design

We integrate specialized fire suppression and NFPA-compliant alarm systems directly into your project’s architectural fabric. We align early with the 2025 Oregon Fire Code and the 2025 Oregon Structural Specialty Code (OSSC) and deliver optimized safety layouts that protect occupants while preserving the visual character of your interior spaces. Our proactive design approach eliminates technical conflicts, ensuring your building remains both aesthetically pure and fully compliant with the evolving Oregon regulatory landscape.

Energy Modeling and Analysis

We utilize advanced energy simulations to ensure strict compliance with the 2025 Oregon Energy Efficiency Specialty Code (OEESC) and ASHRAE 90.1-2022. Our modeling supports Zero Energy Ready initiatives and facilitates expedited COMcheck approval, empowering architects to validate thermal envelope performance and mitigate operational costs well before breaking ground. Our aim remains to improve reliability while reducing interruptions.

Industries National MEP Engineers Supports with Design Expertise

Our designs support flexible tenant fit-outs that meet Portland’s strict energy benchmarking and reporting requirements, while also prioritizing Oregon’s Zero Energy Ready Home (ZERH) standards for urban developments. We also design the high-density cooling and redundant power systems required for the “Silicon Forest”. Our team delivers durable, low-maintenance MEP systems that align with all disciplines and comply with regional specialty codes.

Why MEP Engineering is Important for Your Project

Managing the 2025 Code Transition

With the 2025 OSSC and OMSC becoming mandatory in April 2026, we ensure your designs aren't left behind. Our PEs provide "Code-Forward" engineering that anticipates these updates during the CD production phase.

Achieving Decarbonization Targets

Oregon’s building performance standards are among the most stringent in the US. We help architects implement the heat pump and electrification strategies needed to meet these state-mandated carbon-reduction goals.

Engineering for Seismic Resilience

We provide specialized seismic bracing and anchorage for all MEP systems to meet the strict requirements of Seismic Design Categories D and E, adhering to the 2025 Oregon Structural Specialty Code (OSSC) and ASCE 7-22, and utilizing performance-based analysis to ensure that critical life-safety systems remain operational during and after a seismic event.

High-Efficiency Plumbing Systems

We design advanced non-potable reuse systems that comply with the 2021 Oregon Plumbing Specialty Code and DEQ Recycled Water Rules. Our focus is on integrating Type 3 greywater treatment and rainwater catchment into commercial spaces, helping reduce municipal potable water demand and support LEED and Net Zero Water goals.
